Application filed May 15, 1919. Serial No. 297,419.

To all 'who'in may com not:

lie it lrnown that 1, JOHN E. Hansen, a citizen of the United States, residing at tdpringrfield, in the county of Clark. and titate of Ohio, have invented certain new and, useful. linproveinents in Hovers, of which the following is a specification, reference being had therein to the accompanyinp; drawings.

My invention relates to hovers and more particularly to hovers employing an or] burning lamp.

The object of my invention is to provide an improved hover in which the supply of heat conserved and directed to give the most eiiicient service.

A further object of my invention is to supply an improved hover in which I provide means to prevent its loss by fire.

I have found that when the lamp is burning it generates a gas in the bowl greater in quantity than is consumed by the burner and in the ordinary form of hover this excess escapes into the heating chamber. More attained a certain degree of heat will, ignite and destroy the hover. A

To overcome this I have devised means to prevent the entrance of the gas into the heat ing chamber by venting it to the atmosphere outside the hover.

My invention is adapted to all forms of hovers employing lamps but it is particularly adapted for use in the portable type of hover that is self-contained and can be lifted and moved from place to place.

In this type of hover it is common to provide a vent pipe extending from near the bottom of the heating chamber through the cover to the atmosphere outside the hover. While this irrangement aids radi ation through the bottom of the heating chamber which forms the top of the hover chamber, it causes the accumulation of subject to ignition and destruction. of the hover as hereinbefovc pointed out.

My invention consists of the constructions and combinations hereinafter more fully de scribed and set forth in the claims.

In the accompanying drawings which form a part of this specification Figure 1 is a sectional view of a hover circular in form embodying my invention. Fig. 2 is a crosssection on the line 2--2 of Fig. 1 and Fig.

3 is a fragment of a. side elevation. with the door of the hover removed.

Referring to the drawings 1 represents the side walls and 2 the upper wall or cover of a hover within which there is disposed at heating'chamber 3; and a lalnp chamber a having side walls 5 and a bottom 6 opens into said heating chamber through the bottom T of said chamber.

A space 8 between the outer walls of the hover and the walls 9 and 10 of the heating rhainber is closed by the extensions 7 and 9 forming: a deadair chamber that acts as a non-conductor to keep out the cold and retain the llGl t within the hover.

The bottom 7 of the heating chamber together with a curtain 11 hung from the lower edge of the side walls 1 forms the hover or brooder chamber; and the hover is supported upon legs 12 disposed at intervals about the hover.

The lamp chamber is provided with. a partition 13 having a central opening through which the neck 1% of the burner 15 of the lamp bowl 16 projects.

A door 17 hinged at 18 closes upon the frame 17 of an openlng into the lamp chamber and a slot 19 in the partition 13 permits of the introduction of the lamp into the chamber; and a slide 20 having arms 21 pivoted at their respective ends to said slide and. partition, shown by the dotted lines in Fig. 2 in open position and by the full lines in closed position, forms the means of closing; the slot in the partition. A bar 22 riveted to the partition forms a groove 23 in which the edge of the slide moves.

The lamp bowl is provided with a vent shown in the form of a ti. be with an inlet 24 from the neck of the lamp burner and an outlet 25 into the lamp bowl inclosure; and from this inclosure a pipe 26 leads to the atmosphere outside the hover. Thus it will be seen the excess gases generated in the lamp bowl are prevented from entering the heating; chamber and are vented to the at niosphere outside the hover.

A vent pipe 27 extends from near the iiOOr of the heating chamber through the top of the hover to the atmosphere and a sceen opening 28 in the door of the lamp chamber admits fresh air to circulate through said chamber and pass out through said pipe; and an opening; 29 in the lana chamber wall is provided for the escape of foul air from the brooder or hover chamber. The lamp chimney 30 and the door 17 are provided with mica covered peep holes 31 through which the flame of the Wick 32 may be observed.

A screened opening 33 in the door 17 admits a current of air to the lamp bowl inclosure to keep the bowl cool and carry the gases 01f through the pipe 26.

Having thus described my invention I .1. In a V hover the combination with a lamp chamber having a partition forming a separate inclosure, said chamber and inclosure each having separateoutlets to the atmosphere outside of said hover, of a lamp having its burner in said chamber aboveoutlet to the atmosphere outside of said casing and a lamp having its burner in said lamp chamber upon one side of said partition and its bowl in said inclosure upon the other side of said partition, said bowl having a vent opening into said inclosure.

In a lamp heated hover having an outer casing, the combination of a heating chamber in said casing having an outlet extending from near the bottom of said chamber to the atmosphere outside of said casing and a lamp chamber opening into said heating chamber, said lamp chamber having a partition forming a separate inclosure having an outlet to the atmosphere outside of said casing and a lamp having its burner in said lamp chamber upon one side of said partition and its bowl in said incloane upon the other side of said partition. said how! havnw a vent o )ennn into said inclosurv.

In testimony whereof I have hereunto aiiixed my Signature in the presence of (Wu Witnesses.
